Senate Republicans are threatening to block any bill that continues funding for government operations if it also includes money for the 2010 Affordable Care Act, better known as Obamacare. "This is the last stop before Obamacare fully kicks in on Jan. 1 of next year for us to refuse to fund it," Sen. Mike Lee of Utah said this week.But other Republicans aren't on board: Sen. John McCain, the party's 2008 presidential nominee, said the public is tiring of continuing threats to shut down the government. "Most Americans are really tired of those kinds of shenanigans," he said.Should the GOP carry out its threat? How should Democrats respond? Joel Mathis and Ben Boychuk, the RedBlueAmerica columnists, debate the issue.
